본 발명은 먼지센서부를 가진 전기소제기의 먼지센서검지감도조정에 관한 것이다.The present invention relates to a dust sensor detection sensitivity adjustment of an electric cleaning machine having a dust sensor unit.
최근, 전기소제기의 흡입구와 집진장치 사이의 공기통로에 먼지센서부를 구비하고, 흡입한 공기중에 먼지가 포함되어 있을때에, 상기 먼지센서부가 먼지를 검지하여 먼지의 유무를 표시램프나 음향장치에 의해서 나타내고, 또한 전동송풍기의 회전수를, 먼지나 검출되는 소정의 시간동안, 증가시키는 것이 공지되어 있다.Recently, a dust sensor unit is provided in an air passage between an inlet and a dust collector of an electric cleaner, and when dust is contained in the sucked air, the dust sensor unit detects dust and displays the presence or absence of dust by using a display lamp or an acoustic device. It is also known to increase the number of revolutions of the electric blower for a predetermined time to be detected by dust.
또한, 마루면식별장치에 의하여, '융단'위를 소제할때에는, 마루용흡입구에 설치된 교반기(agitator)를 자동적으로 회전시키고, '판자마루'위를 소제할때에는, 교반기의 회전을 정지시키는 것을 행하고 있다.In addition, by the floor identification device, when cleaning the 'carpet', the agitator installed on the floor inlet is automatically rotated, and when cleaning the 'floor floor', stopping the rotation of the agitator Doing.
그러나, 상기한 바와 같은 구성에서는, 교반기를 회전시키면서 거친 보플을 가진 융단을 소제하면, 먼지가 없어도 융단의 보플을 흡입하여 먼지센서가 보플을 먼지로 검지하게 되므로, 마치 먼지가 융단위에 있는 것처럼 표시를 나타내고, 또한 전동송풍기의 회전수를 증가시키므로 바람직하지 않았다. 따라서, 먼지센서부의 검지감도를 낮추어서, 먼지센서부가 부착되지 않은 종래의 전기소제기와 같이, 소제실감에 맞도록 해서 소제를 행하고 있었다.However, in the above-described configuration, if the carpet having a rough baffle is cleaned while the stirrer is rotated, the dust sensor sucks the baffle of the carpet without dust and the dust sensor detects the baffle as dust. It is not preferable to increase the number of revolutions of the electric blower. Therefore, the detection sensitivity of the dust sensor unit was lowered and the dust was cleaned in a manner similar to that of the conventional cleaning machine without the dust sensor unit, so as to match the cleaning feeling.
소제의 대상물이 융단인지 아닌지에 따라, 먼지센서부의 검지감도를 사용자가 수동으로 조정하여야 하므로 실용적이 못된다고 하는 과제를 가지고 있었다.According to whether or not the object to be cleaned, the user had to manually adjust the detection sensitivity of the dust sensor unit had a problem that it is not practical.
본 발명의 목적은 상기 과제를 해결하기 위하여, 마루면식별장치에 의해 먼지센서부의 검지감도를 자동으로 조정할 수 있는 전기소제기를 제공하는데 있다.SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide an electric cleaner capable of automatically adjusting the detection sensitivity of a dust sensor unit by a floor surface identification device.
본 발명의 구성은, 전기소제기에 있어서, 먼지센서수단과, 마루면식별장치의 신호출력에 의해 상기 먼지센서수단의 검지감도를 조정하는 먼지검지감도조정기와, 소제대상물의 종류를 검출하고, 이 소제대상물의 종류를 나타내는 식별신호를 발생하고, 이 식별신호를, 상기 먼지센서수단의 검지감도를 조정하는 먼지검지감도조정기에, 제어신호로서 인가하도록 사용되는 마루면식별장치를 구비하고 있다.The configuration of the present invention includes a dust sensor means, a dust detection sensitivity adjuster that adjusts the detection sensitivity of the dust sensor means in accordance with a signal output of the floor surface identification device, and a kind of the object to be cleaned. A floor detection apparatus is provided which generates an identification signal indicating the type of cleaning object and applies this identification signal as a control signal to a dust detection sensitivity adjuster for adjusting the detection sensitivity of the dust sensor means.
상기 구성에 의해, 융단위를 소제할때에는 마루용흡입구의 마루면식별장치가 융단을 식별하여 융단의 보플을 흡입하지 않도록 먼지센서의 검지감도를 낮추어서 보플을 먼지로 검지하지 않도록 하므로써 필요이상으로 먼지검지를 표시하지 않고, 또한 전동송풍기의 회전속도가 높아지지 않는다.With the above configuration, when cleaning the fusion unit, the floor surface identification device of the floor inlet identifies the rug and lowers the detection sensitivity of the dust sensor so as not to suck the baffle of the rug so that the baffle is not detected as dust. Without detecting the detection, the rotation speed of the electric blower does not increase.
본 발명의 목적과 효과에 대해서는 이하의 상세한 설명으로 더욱 명백해질 것이다.The objects and effects of the present invention will become more apparent from the following detailed description.

이와 같이 구성된 마루면식별장치(10)에 대해서 그 동작을 설명한다.The operation of the
먼저, '판자마루'위를 소제할 경우에는, 마루용흡입구(18)의 접촉면과 로울러(19)와의 접촉면이 동일하게 되어 로울러(19)에 설치된 로드(20)가 내려와서 스위치(21)는 개방(오프)된다.First, when cleaning the 'floor floor', the contact surface of the
한편, '융단'위를 소제할 경우에는, 로울러(19)가 '융단'의 보플의 반발력에 의하여 밀어올려짐과 동시에 로드(20)도 밀어올려져서 스위치(21)가 닫힌다. 스위치(21)의 개폐신호에 의해서 제어회로(22)가 마루면식별신호를 출력한다. (11)은 교반기를 구동하는 교반기구동용전동기, (12)는 전동기(11)의 구동스위치로서, 마루면식별장치(10)에 의해 개폐된다.

또한, (15)는 전기소제기본체로서, 집진장치와 전동송풍기(13)을 내부에 배치되어 있다. (16)은 호오스이고, (17)은 손잡이조작부로서, 운전스위치(12)등이 설치되어 있다. (18)은 마루용흡입구로서 마루면식별장치(10)와 교반기구동용전동기(11)가 설치되어 있다.In addition,
이상과 같이 구성된 전기소제기에 대해서 이하에 그 동작을 설명한다.The operation of the electric cleaner constructed as described above will be described below.
먼저, 전동송풍기(13)에 의해 기류가 발생하고, 먼지센서부(7)를 통과하는 기류중에 먼지가 있으면, 적외선 LED1로부터 방출되는 적외선이 포토트랜지스터(3) 에 도달하지 않게 되고, 전압의 고저신호가 되어서 먼지센서회로(6)에 인가된다.First, if airflow is generated by the
먼지센서회로(6)에는 표시램프(5)가 접속되어 있으며, 먼지센서부(7)의 기류중에 먼지가 있으면 표시램프(5)가 점등된다. 먼지센서회로(6)에는 그 검지감도를 설정하는 저항기(8)가 접속되어 있다. 이 실시예에서는 저항기(8)의 저항값이 작을수록 검지감도가 높고, 저항값이 클수록 검지감도가 낮아지도록 설정되어 있다.The display lamp 5 is connected to the dust sensor circuit 6, and if there is dust in the airflow of the
다음에, 마루용흡입구(18)에 설치된 마루면식별장치(10)에 의해 '융단'인지 '판자마루'인지의 여부를 판별하고, 소제대상물이 '융단'일때에는 전기신호를 출력하여, 트랜지스터(9)의 베이스(B)에 인가되어서, 트랜지스터(9)의 콜렉터(C)와 에미터(E)를 단락하므로, 저항기(8)의 양단부도 단락하게 되어 먼지센서회로(6)의 검지감도를 낮추게 된다. 또한 동시에 전동기(11)의 운전스위치(12)를 폐쇄하여, 교반기를 회전시킨다. 또한 판자마루일때에는 마루면식별장치(10)으로부터 신호가 발생하지 않고, 트랜지스터(9)의 콜렉터와 에미터(C-E)간이 개방되어, 저항기(8)의 저항값이 변하지 않게 된다. 또한, 운전스위치(12)를 개방하여, 교반기의 회전을 중지시킨다.Next, the
이상과 같이 본 실시예에 의하면 마루용흡입구(18)에 설치된 마루면식별장치 (10)의 신호출력에 의해 먼지센서회로(6)의 검지감도를 마루면에 대응해서 자동적으로 절환할 수 있다.As described above, according to the present embodiment, the detection sensitivity of the dust sensor circuit 6 can be automatically switched corresponding to the floor surface by the signal output of the
다른예로서, 광학적수단(초음파수단)에 의한 마루면식별장치에 대하여 제4a도와 제4b도를 참조하면서 이하 설명한다. 제4a도와 제4b도는 광학적수단(초음파수단)에 의한 마루면식별장치의 개략적인 개념도와 이에 관계되는 출력특성을 도시한 그래프이다.As another example, the floor identification device by the optical means (ultrasound means) will be described below with reference to FIGS. 4A and 4B. 4A and 4B are graphs showing the schematic conceptual diagram of the floor identification apparatus by the optical means (ultrasound means) and the output characteristics related thereto.
마루면으로 향하여 광(초음파)을 발생하는 발광소자(초음파발신소자)와, 상기 마루면으로부터 반사되는 반사광(반사초음파)를 수신하는 발광소자 (초음파수신소자)를 설치하고, 또한 상기 수광소자(초음파수신소자)의 수광량(수신초음파량)에 따라서 출력신호를 발생한다.A light emitting element (ultrasound emitting element) for generating light (ultrasound) toward the floor surface, and a light emitting element (ultrasound receiving element) for receiving reflected light (reflected ultrasonic wave) reflected from the floor surface, and the light receiving element ( An output signal is generated in accordance with the amount of light received (ultrasound amount received) of the ultrasonic wave receiving element).
'판자마루'에서는 광이나 초음파가 모두 양호하게 반사되지만, '융단'에서는 광이나 초음파가 흡수되므로, 반사광량(반소초음파량)이 일정값(α) 이하인 경우에는 융단으로 판별되고, 그 이상인 경우에는 '판자마루'로 판별된다. 이때에, 마루면식별장치의 출력은 트랜지스터(9)의 베이스(B)에 입력된다.In the 'plate floor', both light and ultrasonic waves are well reflected, but in the 'carpet', light or ultrasonic waves are absorbed. It is determined as 'Plan floor'. At this time, the output of the floor identification device is input to the base B of the transistor 9.
이상 설명한 실시예로부터 명백한 바와같이, 본 발명에 의하면 마루용흡입구에 설치한 마루면식별장치와 먼지센서부의 먼지검지감도조정기를 연동하므로서, 융단위를 소제할때에는 먼지의 검지감도를 약간 낮추어서 융단의 보플을 검지하지 않도록 하고, 판자마루나 돗자리를 소제할 때에는 검지감도를 높혀서 효율적으로, 소제할 수 있으므로 그 효과는 지대한 것이 있다.As is apparent from the embodiments described above, according to the present invention, the floor detection device installed at the floor suction port is interlocked with the dust detection sensitivity adjuster of the dust sensor unit. When the baffle is not detected, and the plank floor or mat is cleaned, the detection sensitivity can be increased to effectively clean the baffle.
